1. The hardware buffer is used as a large FIFO during streaming and as a large local ring-buffer during Store-and-Forward mode.

2. Since we have real-time hardware-based compression, we measure captures in 'number of Transitions' rather than ' number of samples.' The number of samples captured varies with the data rate, but is always higher than the number of transitions (#samples ~= #transitions * sample-rate / data-rate). These estimates assume the sample rate is 10x the average data rate. For more information:

Since we have real-time hardware-based compression, we measure captures in 'number of Transitions' rather than ' number of samples.'
The number of samples captured varies with the data rate, but is always higher than the number of transitions
(#samples ~= #transitions * samplerate / datarate).

Typical Transitions captured (USB 3.0)
18ch@250Msps:   100M (@data rates up to 100MTps)  
9ch@500Msps: 100M (@data rates up to 160MTps) 100M (@data rates up to 160MTps)  
4ch@1Gsps: 100M (@data rates beyond full bandwidth) 100M (@data rates beyond full bandwidth)  

Typical Transitions captured (USB 2.0)
36ch@250Msps:   500K (@data rates > 1.0 Tps)
18ch@500Msps:   500K (@data rates > 1.0 Tps)
18ch@250Msps:   100M (@data rates up to 10MTps) 500K (@data rates > 1.0 Tps)
9ch@500Msps: 100M (@data rates up to 14MTps) 100M (@data rates up to 14MTps)

Guaranteed minimum transitions captured (with data rates > 10Tps):

(Ensured by the large store-and-forward buffer, even if the data rate far exceeds the USB bandwidth)
